Issue with Klaviyo Order Confirmation Template in Shopify

[Reading20]

Hi,

I have copied the HTML of a Klaviyo order confirmation template that I created and added it within my Shopify Order Confirmation page. Everything seems fine, however, Shopify is not pulling the order data in the confirmation email that my customers are getting. The product informations are missing.

Is there a way to fix this?

Thanks!

I tried to contact Shopify Support but they asked me to come here. Any ideas? Thanks!
